title: Fully updatable three-dimensional holographic stereogram display device based on organic monolithic compound.
abstract: Holographic technique is a unique method to reproduce object on a device in three dimensions (3D). It allows us real 3D images with full parallax without special eye glasses or any special optical devices. we present fully updatable holographic 3D display system using a holographic stereographic technique with a transparent optical device of poly(methylmethacrylate) doped organic compound of 3-[(4-nitrophenyl)azo]-9H-carbazole-9-ethanol (NACzE). 100 elemental holograms which are a series of pictures of object took from different angles can completely reproduce updatable entire hologram of object. Former hologram of object can be over-recorded and immediately replaced by new hologram of object without erasing process. Typical recording time for an elemental hologram is 200 ms, and total recording time including translational stage movement for 100 elemental holograms is 28 s. The present system with preferred memory is a good candidate for 3D signage application.
